The 1966 300 Series received a facelift over the 1965 model. The front and rear styling was updated with a more sculpted look. The crossbar grille was deeply set in the facia. Wraparound taillights were unique to the 300 Series this year. Cast trim pieces inset into the front fenders continued into the front doors.

Standard engine was a 383 4-barrel engine with 325 horsepower and a new 365 horsepower 440 T.N.T engine became available.
